摘　　要：水声应答机采用电池供电,长时间工作在水下,需要在可靠应答测距基础上降低功耗。应答机采用值更-检测工作模式并合理分工,以MSP430单片机为基础设计值更电路。值更电路关闭一切不必要的电路,仅检测水上系统的控制指令,并给出回复。经实验验证在8 Ah供电条件下,应答机在满足应答功耗之外待机时间超过30天。值更电路性能稳定,功耗低,满足设计要求。Acoustic responder works underwater in a long period and is supplied by batteries. It needs to reduce its power consumption in the precondition of responding the range detection credibly. The responder uses watching-detecting mode and di-vides the two functions in reason. The watching circuit is designed on the basis of MSP430 MCU,which shuts down every unnec-essary circuit,but detects and replies the control instructions only. The experimental results validate that the responder with 8 Ah is on standby in more than 30 days under the condition of meeting response consumption. The watching circuit has stable per-formance and low-power consumption,and meets the design requirement.
